SEO: Hiding SEO content

I've read on numerous websites that google does all kind of fancy tricks to check if you are trying to hide your content. I know for a fact that you can fill a div with content, and then replace the content of that div with javascript, and still the initial content will be indexed!

Batfile: Open directory in console

Whenever i download a small commandline tool, i need to open the program via the.. commandline =)

Before i copied the path of the explorer , then opened Commandline prompt via startmenu. Then paste the path, to finally end up in the path of the commanline tool, and then start testing..

This was then.. now i have a small batfile in my SendTo menu, this way i can select any file or folder and "send" it to the batfile, and commandline promt will open in that particular directory. SWEET!

@ECHO OFF
dir %1 | FIND "%~f1" > IS_DIR.res 
set isFolder=0
for /f "tokens=*" %%T in (IS_DIR.res) do set /a isFolder=isFolder+1
DEL /S /Q /F "IS_DIR.res"
CLS
IF %isFolder% == 1 (
 CMD /k cd /d "%~f1"
) ELSE (
 CMD /k cd /d "%~dp1"
)

PHP : getFileExtension()

Stumbled upon this article at Cowburn. It's about the simple task of getting the extension of a filename.
It highlights this pretty nifty function:

return pathinfo($p, PATHINFO_EXTENSION);

In my case i needed it to handle filenames with queryline attached as well, simple fix:

function getFileExtension($p) {
 if( strpos($p,"?") != '' ) $p = substr($p, 0, strpos($p,"?") ); 
 return pathinfo($p, PATHINFO_EXTENSION);
 }

//==EXAMPLE==
wscript.echo getFileExtension("http://mysite/page.php?thefile=readme.txt")
// Outputs : 'php'
